After gaining reputable achievements in the full IP field, including patent and trademark prosecution and litigation, the firm has built departments for corporate matters and general laws.

Trade Secret
Family Laws

IP is the main international areas of practice of the firm. As is known, there is getting more and more competition in the world. To be outstanding from the vast competing peers, each firm should have its own surviving features. The firm’s survival skills are founded on cultivating abilities of their colleagues to provide competent or incomparable services. The firm uniquely show their competence by the following offers, e.g. 1) sending the firm a pending or granted patent for their comments as to how the firm can improve the claims, 2) sending the firm a pending patent specification without the claims for the firm to draft the claims for the client’s comparison with the original claims, or 3) sending to the firm and the current firm the client is at the same time an initial disclosure so that the client can compare and find out which firm can provide the better claims.

As to the firm’s legal department, although the world is such diversified that each field needs much competence and knowledge, the firm uses the same mindset as the IP department for providing their services. The legal department mainly focuses services in corporate matters and family laws.
